Planetary radius versus stellar metallicity [Fe/H] (dex) (left panel), and as a function of planet equilibrium temperature T_eq (K) (right panel). Black points indicate known planets, planets in the mass range 0.2 < M_pl < 0.7 M_J are indicated by Turquoise points. Black and turquoise dashed lines are a simple linear regression to the two samples. Data were taken from the exoplanet encyclopaedia. Known planetary systems with characteristics across the parameter space are indicated as in Fig. 18. Our three new discoveries are indicated by fuchsia filled circles.
